Carbon Dioxide
TVA's 2023 system Carbon-emission rate of 624.94 lbs/MWh. This rate includes emissions and generation from TVA generating assets and purchased power. The CO2 rates disclosed reflect TVA's 2023 renewable energy credit (REC) adjustment, which resulted in a reduction of 2.76 percent in the CO2 lbs/MWh. For formal disclosure of customer CO2 rates appropriate for carbon accounting purposes, please contact TVA or your local power company directly.
As the nation's largest public power company, TVA delivers reliable and competitively priced power to 153 local power distributors, 54 large industrial customers and seven federal installations.
These customers are interested in the CO2 intensity (or "carbon footprint") of the power they're buying. In addition, many stakeholders are interested in comparing the CO2 performance of various electric utilities of different sizes.
As a service, TVA provides as-delivered CO2 emission rates to its customers and stakeholders in a manner consistent with generally accepted carbon accounting standards, such as the Climate Registry's Electric Power Sector Protocol for the Voluntary Reporting Program and the new World Resources Institute and World Business Council for Sustainable Development's Greenhouse Gas Protocol's Scope 2 Guidance.
